lt is one oit' the objects ot my invention to provide a construction oit this type yin which the tightening ot' the ancl'ior upon its transverse movement with respect to the rail is eliecl'ed both by reason ot a `ditlierential movement of the jaws or arms at opposite sides ot the ait and also by reason ot a dittlerenial lcverag .i otl thev arms at opposite sides ot the rail. f

it is another ol'iject ot in v invention tov provide an iu'iprored -lorm oit device Yfor causing dil'lierential movement oi' the arnis or jaws at the opposite sides.

1t is still another object ot my invention to improve devices ot this type in Sundrykdetails hereinatter pointedout. The preterred means by which I have accomplished my several objects are illustrated in the drawing and are hereinafter specifically described. That which I believe tobe new ant desire to cover by Letters Patent is sety forth in the claims. A A

In the drawing-q Fig. 1 is a face view of one Vform of my vimproved anchor in operative positionon a rail, the rail being` shown in cross section with the head of the rail broken away, the normal shape of the body o'll the anchor from which it is distorted in its application to the rail being indicated by dotted lines. j

Fig. 2 is a view similar to Fig.y 1, but illustratingthe use ot a modified tornooi? deviceV for holding the anchor from loosening on the rail.

Fig. Skis another viewrsimilar to Fig.` 1,

the type ot ancho-r shownin myy application but showing another modilied rform of wedge device.

y Fig. l is a view similarr to Fig. 1, but showing' still another `Inodilied form of wedge de? vice; and

Fig. 5 is a'view showing the outline of the rblanlt from 4which the wedge device of Fig. "el is formed.`

Referring to Fig. 17 10 and 11 indicate the flanges at'the opposite sides oi"l a rail, and 12 indicates the web ot the rail, the upper faces ot the flanges 10 and 11 beingsloped as is usual rin connection with American railroad rails. 13 indicates the body. of the anchor device, having abearing 1li against the bottom face oli the rail, andv beingbent inwardly at its ends yto kprovide aws or arms 15 and 1o adapted topress downwardly upon the uppei'iaces of the flanges 10 and 11, such downwardy pressure being applied either by directcontact ot the jaw with the. ifiange .or by the use ot' an interposed yplate or 'wedge 17. rlll/ie anchor is preferablyfapplied y to the rail. closelyadjacent to the crosstie 18, as is usual with devices of this type. In the `(.'onstrnction `illustratechthe plateA 17 interposedbetween the j aw `16 and the upper face ot= the flange 11, is in the for-moi a wedge with its thicker portion disposed` adjacent to the outer tace. oit the flange. The wedge 1'? is provided with .a downward extension 19 at its outeredge', adapted to engage the outer face ot the flange 11. As is shown by dotted lines in Fig. 1. the normal shape of the anchor device is such that the bearing 1/1 would normally stand at some little .distance above the bottom face of the` rail, in the appliedk position ot the anchory-the arrangement being such in this regard that it is vnecessary to distortthe anchor bymoving the bearing 14 downwardly witlrrespect to vthe ends of the jaws 15 andltq against the resilient action of ythe bar]4 making upthe anchor device, in the application of the device to the rail.

, 4The device of Fig. 1' is applied to the rail in the well understood manner.y The; jaw 16 is .first applied to the flange 11, with the end of the jaw 1,6 adjacent to the web 12 of the rail, and the wedge 17 is inserted underneath the jaw. The anchor is then `raised to bring the jaw 15` into engagement withv the edgevot the flange 10, whereupon the body of the anchor isy driven or v,otherwise forced toward the right in Fig. 1` for bringing the parts to the position shown in said gure,the wedge 17 meanwhile being held` in any suitable manner in position upon the flange. lt will be understood that the wedge l? lis of suliicient size longitudinally of the rail as to provide bearings at opposite sides ofthe body7 of the anchor for the desired purchase upon the wedge for holding it in position. When the end of the jaw 16 snaps intok engagement with the shoulder 20 provided on the upper face of the wedge, the body portion of the anchor is, of' course, prevented normally from moving again toward the left in said'figure, the anchor being thus prevented from loosening on the rail. f

As will be readily understood, in the application of the` device to the rail, the tightsning of the ancho-r is due in part to the fact that when the body ofthe device moves toward the right in Fig. 1, the arm or jaw 15 is moved Vupwardly upon the upper yface of the flange 10, while the arm or j aw 16 and the bottom bearing 14 are moved substantially horizontally. inasmuch as the parts are arranged and proportioned so that the device fits tightly upon the rail when .first applied thereto and before the transverse movement as described, it will be unyderstood'that the transverse movement results in a distortion of the anchor, serving to tighten the device very effectively upon the rail. yEhe shoulder 2O isto be of such a size as toA serve normally for preventing disengagement of the end of the jaw 16 therefrom after such jaw has snapped into engagement therewith.

lt will be understood, however, that when the anchor is to be removed from the rail, the jaw 16 can be readily moved upwardly out of engagement. with the shoulder 2O by the application of upward pressure thereon.

A further tightening effect upon the transverse movement ofthe body of the anchor toward the right in Fig. 1, is produced by reason of the differential leverage at opposite ends ofthe device; that is to say, by reason ofthe Afact that the distance between the bearing 14 and the end of the jaw 15 is'considerably less than the distance between the bearing 14 and the end of the iai-w16.

VThe anchor device of Fig. 2 is similar to that shown in Fig. 1, by which a. differential leverage is provided at opposite sides of therail. but -a`diflferent form of device is provided for preventing the loosening fmovement of theanchor upon the rail after vits application.

The form of device here shown comprises a plate `21 lprovided with a shoulder 22 pressed in the upper face of' the plate, the arrangement'beingsuch that the effective thickness of' the plate 21`is the same "at the' outer edge of the flange ras that at the inner edge of the plate adjacent to the web 12. rllhe plate 21 is thus not relied upon for tightening the anchor, but only for holding the anchor against moving in direction for loosening the anchor upon the rail.

ln this construction, however, the anchor is tightened by reason of the differential leverage. is will be readily understood, in the transverse movement of the body of the anchor toward the right in Fig. 2, the end of the jaw 16 is moved downwardly substantiallythe same distance as the'end of the jaw 15 is moved upwardly. The body of the anchor has accordingly been given a slight rocking movement in clockwise direction-in said ligure, during such transverse movement into operative position. lt will beunderstood, however, thatby reason of the differential leverage of; the device at opposite sides of the rail, it would have been necessary for the jaw 16 to move dowi1- wardy a. greater distance than the jaw 15 moved upwardly if such movement were to be effected without distortion of the dcvice. lt is, therefore, clear that upon the transverse movement the anchor is tightened, sincethe j aw 16 is unable to have such greater downward movement.

ln Fig. 3 l have shown a modified form of wedge device 28, tlie'same being formed of sheet metal bent into shape for providing a shoulder 24 supported by the underlying turned edge portion 25 of the metal.v

ln Fig. 4, l have shown still another forni of wedge device 26, having a shoulderv 2T supported by the underlying` turned edge portion 28. The plate 26. however, does not extend to the web 12 of the rail for as does the plate 23 of the form shown in Cla lOl)

F 3, but such inward movement of the i plate 26 is prevented bythe use of arms'or hooks 29 which engage the yedge of the flange 11, the arms or hooks ,29,being formed integrally with the plat-e 26, as is best shown in Fig. 5. r

llfhile I prefer to employ one of the con structions as illust-rated in the several figures of the drawing. it will be Vunderstood that I do not wish to be'restricted to the use of vsuch constructions, except so .far as the same are specifically claimed, since it is evident thatmany changes may be made in the details of the constructions, without ,1`
